Sniper Country Duty Roster collective wisdom


Global Positioning Systems:


Since I can't afford a laser range finder and probably wouldn't help in the tall grass anyway...let me show how old I might be and ask a question about GPS devices. Am use to the "old" magnetic compass and usually carried TWO, the one issued and a Silva, just in case the Mil-spec one was off....whats the latest poop on GPS's any any preferences??? I mean ,way back when, the worst problems I ever had about getting into an AO was the Air Farce dropping us in the wrong DZ !! Or the Army "rotorheads" landing 20 klicks off and swearing they were right on target. Just the usual mundane situations...SNAFU !!! mabe that will get a good discussion going.

Will: Garmin makes an excellent GPS. It is my favorite because I am also a private pilot and this brand is well suited for both flying and ground Nav. Megellan may be better at purely ground ops as they seem to have a better visual for walking. I havenít played with one much so I can not say for sure. Garmin is excellent and a breeze to fly with. It does a respectable job at land nav.

What about some "real-time" feedback on GPS as far as how close the waypoints can be if navigating Flat but covered terrain , such as a southern swamp !!!

Will Adams... on GPS, the signals from the satellites are able to give your position to within arms reach... maybe less.
The Gov't introduces a "jitter" to protect us from ourselves. The military units filter out this jitter for their equipment. I have a new Magellan 4000XL which also gives me the current error I'm receiving from the "jitter"... it is typically 20 to 75 feet, the worst it has ever been was 128 feet.

So, when their spotters have you, and you're trying to find your hide, you'll know how big a circle you have to look in...

Someone asked about GPS. I have found the cheap commercial ones don't have enough antenna sensitivity to pick up enough satellites to always give a good reading. Two years ago when elk hunting in the rain, I could get "action" on the GPS in clearings, but zip-all under the leaf cover. Then again, a friend's Eagle has all the settings to tell you ground speed when operated in a vehicle.

On another topic; we had a bad day at the office on Thursday. Two of our jets had a midair collision. One stopped flying, pilot got out of the formation, ejected but did not survive. Other aircraft returned to base. Yours truly headed for his duty station in the base CP. Of interest to the question on GPS; has anyone ever seen a TEN-figure grid reference before? That is what the ground search party reported as the crash site. That would be accuracy to the meter. Obviously they weren't using a cheap commercial unit.

GPS I think what hunter's and sniper's need is a GPS that can be used during a stalk to allow you to circle a position without looking up ever 10' and come back to a position on a map or grid that will allow you to stay concealed until you have to make the final shot or observation. I have located game many times and had to change the approach due to wind or other reasons only to stalk 50 or 100 yards off target and get spotted before I could even find the target again.
If it could be programed say " go 389 yards at 143 degrees " and have it bring you to this point like the "go back to camp function" it would be invaluable if it would work properly. To make that mistake stalking men would be fatal. Bet they have something like that by now? If you have a map it would be simple enough to go a few clicks and convert it I guess but just to put the meter/yards in and the angle and have it read a new position would be super if you get my drift.

Bill: They do indeed already have GPS that'll do just what you mentioned. As for the guy who asked about the 10-digit grid from GPS; yep, heard it. Put it on "average" and let it sit on the deck for 5 minutes or so at that spot. With a little luck, it'll pick up enough satellites to give you that kinda accuracy. In fact, a time is coming when all that fancy, time-consuming survey stuff that artillery units have to do is replaced by a GPS receiver on every single gun. And it's not that the commercial units are cheap---they are probably capable of the same kinda accuracy. But think how a smart guy could wire a GPS with an accuracy of +/- 1 m into a Scud missile, as part of a guidance system, and have a poor man's Tomahawk. See why our govt. isn't big on commercially available units with that kinda accuracy? So they deliberately screw up the signal a little, and don't tell civilian manufacturers how to un-screw it.

On GPS. I fly an ag plane kept on target by a civilian built and sold GPS. It's accurate to 3 feet with differential lock.
Can the bad guys buy one for thier scuds? Yes. But they cost around $14,000 vs $99.95. So why does the government scramble the signal? Another conspiracy, to make us spend more money with the GPS manufacturers. After all, who is building the government GPS systems? I guarentee its not the Army, Navy, Air Force, or even the great Marines. It's the ciVILLAN contractors. HA

PS: don't take all this seriously, I'm just P***ed about a $3500 repair bill this year for my GPS

Will,

I have a webpage with info on GPS receivers below. The Russian GPS system GLONASS is available to the civilian market here, and NO they don't jiggle the signal. Only one company offering units capable of receiving the GLONASS signals though. The Garmin model 12 ($150.00) and 12XL ($250.00), are the most popular units. 12 channel receiver, very easy to learn functions. Outstanding customer service.
